摘要
通过实验对比了三种化学除磷药剂的总磷去除效果,确定最佳除磷药剂为氯化铁。通过进一步的总磷去除实验,确定当氯化铁投入量为353.57~400 mg/L时,就可以确保总磷6.8 mg/L水样的出水总磷小于0.5 mg/L,达到一级标准排放。同时提出后置除磷的方法,为双氧水企业废水除磷提供了参考。
In this paper,the total phosphorus removal efficiency of three chemical phosphorus removal agents which was compared by experiments, and determine that iron chloride is the best phosphorus removal agent. Through further study, it was determined that when the input amount of iron chloride was 353.57 to 400 mg/L,the total phosphorus of the water sample that total phosphorus is 6.8 mg/L could be ensured to be less than 0.5 mg/L,which to achieve the first-level standard discharge. In addition,the method of dephos- phorization by post-setting is put forward,which provides a reference for phosphorus removal from wastewater in the hydrogen peroxide factories.
